Chapter 1 -- Safety Considerations--Replacing the AC Power Line Fuses
1 - 4
If you are changing between 100 and 120 Vac, or changing between 220 and 240 Vac, you do not
need to change the fuses. All other changes require a fuse change. See Table 1-3 for the correct
fuse for each line voltage setting.
If you are uncertain of the fuse value that you currently have in the ECM8 you can easily remove
the fuses and check them. Use your screwdriver to gently pry up the two plastic arrows in the line
voltage selector. These arrows are on top of fuse holders. Once a fuse holder is up about 1 cm
you can grab it with your fingers and remove it. The fuse's value will be written on the fuse.
When you replace the fuse and its holder make sure the arrow points towards the bottom of the
ECM8.
7) Close the cover of the AC input module. It should snap into place.
8) Check the line voltage setting displayed in the small window on the AC input module. It must be
the one that you desire. If it is not, repeat steps 4 through 8 of this procedure.
Replacing the AC Power Line Fuses
This section of the ECM8 manual gives step-by-step instructions for changing the AC power line fuses in
your ECM8 Electrochemical Multiplexer. Please follow these instructions carefully. You will need a small
flat blade screwdriver to perform this procedure.
1) Unplug the AC power line cord from the back of the ECM8. The fuses cannot be changed with
the AC line cord plugged into the ECM8.
2) Locate the AC input module on the upper left hand corner of the ECM8 rear panel. It can be
identified by the line cord connector built into it.
3) Find the small slot on the right side of the AC input module near the line voltage setting window.
Place the blade of a small screwdriver in this slot and pry open the AC input module.
4) The fuses are contained inside two fuse holders. The tops of the fuse holders are black plastic with
a white arrow on them.
Use your screwdriver to gently pry up the plastic portion of the fuse holders. Once the fuse
holders are up about 1 cm you should be able to grab them with you fingers and pull them
completely out of the AC input module.
5) Remove the old fuses by prying them out of the fuse holders. Replace them with the correct fuses
which simply pop into the fuse holders. The fuse orientation in the fuse holder is unimportant.
Replace the fuse(s) only with the correct value and type of fuse. See Table 1-3 and the text
preceding it for fuse values and type descriptions.
6) Replace the fuse holders (with the correct fuses) in the AC input module. The arrows on the fuse
holders must point towards the bottom of the ECM8.
7) Close the cover of the AC input module. It should snap into place.
